Los Che had set Mustafi’s asking price at £30m, yet the Gunners could land the 24-year-old for significantly less after Valencia chief Garcia Pitarch admitted that the La Liga outfit are currently failing to meet FFP regulations.

Pitarch said: “We’re above the FFP guidelines, that’s the reality, and as of today, the four players we’ve signed cannot be registered, meaning we need to reduce the cost in a significant manner to register the players and sign a centre-back, which is a priority in case one of the ones at our club leaves.”
